The cost of seeing a weekday show is 2/3 the cost of a weekend show. in one month, andy spent $42.50 for 4 weekday shows and 3 weekend shows. find the price of a weekday show and the price of a weekend show

 x = weekday shows
y = weekend shows

x = 2/3y
4x + 3y = 42.50

4(2/3y) + 3y = 42.50
8/3y + 3y = 42.50
8/3y + 9/3y = 42.50
17/3y = 42.50
y = 42.50 * 3/17
y = 127.50/17
y = 7.50

x = 2/3y
x = 2/3(7.50)
x = 15/3
x = 5

so weekday shows (x) cost $ 5 and weekend shows (y) cost $ 7.50

Ion know honestly good luck tho jhit
